Abstract

Self bondable polyamides are prepared by reacting an aromatic diisocyanate or diamine with a mixture of terephthalic acids and one or two aliphatic dibasic acid having at least 6 carbon atoms and a monocarboxylic acid. These self bondable amides can also be used as topcoats for wires having basecoats of another polymer, e.g., a polyester, polyester-imide, or polyamide-imide.
